本文主要阐述了DTMF的原理及如何在MATLAB上产生DTMF信号，主要涉及到电话拨号音合成的基本原理及识别的主要方法，利用 MATLAB 软件以及 FFT 算法实现对电话通信系统中拨号音的合成与识别。并进一步利用 MATLAB 中的图形用户界面 GUI 制作简单直观的模拟界面。 能够利用矩阵不同的基频合成 0 － 9 不同按键的拨号音，并能够对不同的拨号音加以正确的识别，实现由拨号音解析出电话号码的过程，完成对电话拨号音系统的简单的实验仿真。-This paper described the principle and how DTMF in MATLAB to generate DTMF signals, mainly related to the telephone dial tone of the basic principles of synthesis and identification of the main methods, the use of MATLAB software and the FFT algorithm on the telephone communication system dial tone Synthesis and Recognition . And further the use of MATLAB in the production of graphical user interface simple and intuitive GUI interface simulation. Able to take advantage of matrix synthesis of different fundamental frequency 0- 9 different keys of the dial tone and be able to different dial tone to be the correct identification, the dial tone from a telephone number to resolve the process of completion of the telephone dial tone system, a simple experiment simulation

vc写的一个终端程序，可支持telnet和串口，标准终端协议。功能很全，且运行稳定。-vc write a terminal program, to support telnet and serial, standard terminal agreement. All very functional, and stable operation.

该工程创建为动态链接库，主要实现客户端通信（clientsocket）1.通信初始化2.创建套接字，套接字地址3.指定客户端端口号4.相应的动态API接口。

1、  系统里面没有安装Java运行时环境（JRE）的先安装“安装文件”文件夹下的JRE6.0。（JDK6.0里面包含有JRE6.0） 2、  然后将“运行”文件夹下面的“lib”文件夹和P2Pcommuni- cation.jar文件复制到同一个文件夹里面，双击运行P2Pcommunication.jar文件即可启动一个程序。
